Cleveland Orenthal Brown, Jr., commonly referred to as Cleveland, Jr., is the son of Cleveland and Loretta Brown. He was first depicted as a very hyperactive boy and speaks quickly, with a rather short attention span.
He has a cameo appearance in "Ready, Willing, and Disabled" where he can be seen cheering when Joe recovers the money stolen by the car wash thief.
In "Love, Blactually", the animatic for that episode in DVD Vol. 7 shows him in his present enlarged state which was revealed to be caused by Ritalin. The entire scene was dropped when the ending of the episode was changed.
Cleveland, Jr. became a main character in The Cleveland Show. Both Cleveland and Cleveland, Jr. left Family Guy, when The Cleveland Show premiered. In the pilot, Cleveland, Jr. has turned 14 and changed completely from how he was originally portrayed. Where before he was small, slim, and hyperactive, Cleveland, Jr. is now an obese teenage boy, wears glasses, and speaks in a much deeper, slower manner, much more in turn with his father. In essence, this makes him the series' version of Chris Griffin, but potentially smarter. Originally voiced by Mike Henry, Kevin Michael Richardson has become the new voice actor for Cleveland, Jr. to accommodate for these changes.
Peter accidentally shoots Jr. in "A Shot in the Dark" when he mistakes him for a thief trying to break into the Brown home by climbing through a window as Cleveland discourages opening the door to the air conditioning out. The family insists that Peter go on trial for hate crimes and his attempts to repair the damage makes things worse. Carter Pewterschmidt's lawyer manages to convince the courtroom that Jr. is a thug, and the locals nearly run the family out of town until Peter steps forward and notes that he DID shoot Jr., but Cleveland's claim of also shooting him causes the crowd to disperse, disinterested in black-on-black crime. Peter apologizes to Jr. and it is accepted until Cleveland leaves, then he threatens Peter, laughs it off and then leaves him wondering if he is joking or not.
